Ubuntu Security Notice USN-1598-1
October 09, 2012

linux vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 8.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 8.04 LTS:
linux-image-2.6.24-32-386 2.6.24-32.105
linux-image-2.6.24-32-generic 2.6.24-32.105
linux-image-2.6.24-32-hppa32 2.6.24-32.105
linux-image-2.6.24-32-hppa64 2.6.24-32.105
linux-image-2.6.24-32-itanium 2.6.24-32.105

linux-image-2.6.24-32-powerpc64-smp 2.6.24-32.105
linux-image-2.6.24-32-rt 2.6.24-32.105
linux-image-2.6.24-32-server 2.6.24-32.105
linux-image-2.6.24-32-sparc64 2.6.24-32.105

linux-image-2.6.24-32-virtual 2.6.24-32.105
linux-image-2.6.24-32-xen 2.6.24-32.105

After a standard system update you need to reboot your computer to make
all the necessary changes.

Ubuntu Security Notice USN-1599-1
October 09, 2012

linux-ti-omap4 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

The system could be made to run actions or potentially programs as an
administrator.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

Pablo Neira Ayuso discovered a flaw in the credentials of netlink messages.
An unprivileged local attacker could exploit this by getting a netlink
based service, that relies on netlink credentials, to perform privileged
actions.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
linux-image-3.2.0-1420-omap4 3.2.0-1420.27

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
